Deep Circumflex Iliac Vein
The deep circumflex iliac vein is formed by the union of the venae comitantes of the deep iliac circumflex artery. It drains venous blood from the walls of the iliac fossa. It empties into the external iliac vein about 2 cm superior to the inguinal ligament, just distal to where the inferior epigastric vein does so. The DCIV runs across the external iliac artery The external iliac arteries are two major Artery, arteries which bifurcate off the common iliac arteries anterior to the sacroiliac joint of the pelvis. Structure The external iliac artery arises from the bifurcation of the common iliac arter .... It forms anastomoses with the iliolumbar vein, and lower two lumbar veins.

External Iliac Vein
The external iliac veins are large veins that connect the femoral veins to the common iliac veins. Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins (to form the common iliac veins). Both external iliac veins are accompanied along their course by external iliac arteries. Structure A continuation of the femoral vein, the external iliac vein starts at the level of the inguinal ligament. It runs beside its corresponding artery and along the brim of the lesser pelvis to unite with the internal iliac vein anterior to the sacroiliac joint where it forms the common iliac vein. The left external iliac vein remains medial to the artery along its whole path. The right external iliac vein is medial to the artery, but as it ascends, it runs posterior to it. The external iliac vein is crossed by the ureter and internal iliac artery which both extend towards the middle. In males it is crossed by the vas deferens and ...

Deep Circumflex Iliac Artery
The deep circumflex iliac artery (or deep iliac circumflex artery) is an artery in the pelvis that travels along the iliac crest of the pelvic bone. Course The deep circumflex iliac artery arises from the lateral aspect of the external iliac artery nearly opposite the origin of the inferior epigastric artery. It ascends obliquely and laterally, posterior to the inguinal ligament, contained in a fibrous sheath formed by the junction of the transversalis fascia and iliac fascia. It travels to the anterior superior iliac spine, where it anastomoses with the ascending branch of the lateral femoral circumflex artery. It then pierces the transversalis fascia and passes medially along the inner lip of the crest of the ilium to a point where it perforates the transversus abdominis muscle. From there, it travels posteriorly between the transversus abdominis muscle and the internal oblique muscle to anastomose with the iliolumbar artery and the superior gluteal artery. Opposite the ...

Venae Comitantes
Vena comitans (Latin for accompanying vein, also known as a satellite vein) refers to a vein that is usually paired, with both veins lying on the sides of an artery. Because they are generally found in pairs, they are often referred to by their plural form: venae comitantes. Venae comitantes are usually found with certain smaller arteries, especially those in the extremities. Larger arteries, on the other hand, generally do not have venae comitantes. They usually have a single, similarly sized vein which is not as intimately associated with the artery. Function As the vein is found in close proximity to an artery the pulsations of the artery aid venous return. Claude Bernard suggested the interchange of heat between the arteries and adjacent veins might moderate cooling of the arterial blood, for which there is experimental evidence. Examples Examples of arteries and their venae comitantes: * Radial artery and radial veins * Ulnar artery and ulnar veins * Brachial artery a ...

Iliac Fossa
The iliac fossa is a large, smooth, concave surface on the internal surface of the Ilium (bone), ilium (part of the three fused bones making the hip bone). Structure The iliac fossa is bounded above by the iliac crest, and below by the Arcuate line (ilium), arcuate line. It is bordered in front and behind by the anterior and posterior borders of the Ilium (bone), ilium. The iliac fossa gives origin to the iliacus muscle. The obturator nerve passes around the iliac fossa. It is perforated at its inner part by a nutrient canal. Below it there is a smooth, rounded border, the arcuate line (ilium), arcuate line, which runs anterior, inferior, and medial. When the "left" or "right" adjective is used (e.g. "right iliac fossa"), the iliac fossa usually means one of the groin, inguinal regions of the Quadrants and regions of abdomen, nine regions of the abdomen.

Inguinal Ligament
The inguinal ligament (), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. Structure The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. Structures that pass deep to the inguinal ligament include: * Psoas major, iliacus, pectineus * Femoral nerve, artery, and vein * Lateral cutaneous nerve of thigh *Lymphatics Function The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint ...

Inferior Epigastric Vein
In human anatomy, inferior epigastric vein are 1-2 veins accompanying the inferior epigastric artery. They drain into the external iliac vein just proximal to the inguinal ligament.

External Iliac Artery
The external iliac arteries are two major Artery, arteries which bifurcate off the common iliac arteries anterior to the sacroiliac joint of the pelvis. Structure The external iliac artery arises from the bifurcation of the common iliac artery. They proceed anterior and inferior along the medial border of the psoas major muscles. They exit the Pelvis, pelvic girdle posterior and inferior to the inguinal ligament. This occurs about one third laterally from the insertion point of the inguinal ligament on the pubic tubercle. At this point they are referred to as the femoral arteries. Branches Function The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the inguinal ligament in the lower part of the ...

Iliolumbar Vein
The iliolumbar vein is the vena comitans of the iliolumbar artery. The obturator nerve crosses superficial to it. A single vein is found more commonly than a double vein. It drains vertebral segments four and five. It is closely related to the ascending lumbar vein The ascending lumbar vein is a vein that runs up through the lumbar region on the side of the vertebral column. Structure The ascending lumbar vein is a paired structure (i.e. one each for the right and left sides of the body). It starts at the c ....

Lumbar Veins
The lumbar veins are four pairs of veins running along the inside of the posterior abdominal wall, and drain venous blood from parts of the abdominal wall. Each lumbar vein accompanies a single lumbar artery. The lower two pairs of lumbar veins all drain directly into the inferior vena cava, whereas the fate of the upper two pairs is more variable. Lumbar veins are the lumbar equivalent of the posterior intercostal veins of the thorax. Structure A lumbar vein accompanies each of the four lumbar arteries on each side of the body. Distribution and tributaries Collectively, the lumbar veins drain blood from the territories supplied by the corresponding lumbar arteries (the posterior, lateral, and anterior abdominal wall). The lumbar veins drain the anterior spinal veins. Fate The 3rd and 4th lumbar veins drain into the inferior vena cava. The fate of the two superior lumbar veins is far more variable, and may drain into either the inferior vena cava, ascending lumbar v ...
